CAUTION: To ensure proper system cooling, memory-module blanks must be installed in any memory socket that is not occupied. Remove
memory-module blanks only if you intend to install memory in those sockets.
NOTE: Hot-swap removal or installation of the fans is not supported.
NOTE: In the event of a problem with a particular fan, the fan number is referenced by the system's management software, allowing you to easily
identify and replace the proper fan by noting the fan numbers on the fan assembly.
WARNING: The cooling fan can continue to spin for some time after the system has been powered down. Allow time for the fan to stop spinning
before removing it from the system.
WARNING: Do not attempt to operate the system without the cooling fan.

authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not
authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
